海南木莲总黄酮含量的测定

Determination of total flavone content in manglietia hainanensis dandy

利用分光光度法测定了海南木莲中的总黄酮含量,结果表明:海南木莲叶中总黄酮的质量分数为5.78%,RSD=2.62%(n=6);枝中为3.05%,RSD=2.16%(n=6).回归方程A=7.901 4c+0.002 8,相关系数r=0.999 9.本法操作简便,测定结果稳定、准确,为开发利用海南木莲药用提供了科学依据.

Spectrophotometry was used to determine the flavone content in manglietia hainanensis dandy, The results were w = 5.78 %（RSD = 2.62 % ）in leaf and w =3,05 % （ RSD = 2. 16 % ） in stem of mangliefia hainanensis dandy, The regression equation was A =7.901 4c ＋0,002 8, r = 0.999 9, The .method has such advantages as high sensitivity and stability.
